เครื่องนับจำนวนแบบดิจิตอล Digital Counter
รุ่น 54U Series
คุณลักษณะ
The Codix 54U is a voltage-powered dual function counter with 4 functions in one device: Counter with 2 totalizing ranges, totalizer and timer, totalizer and frequency meter, timer with 2 time ranges. For fast and slow count pulses, with 6-digit LED display for NPN, PNP input signals.
- Fast count and frequency input – input frequency max. 60 kHz (can be damped to 30 Hz for mechanical contacts).
- Robust housing – IP65 protected.
- Very bright LED display, 14 mm high, 6 digits.
- Very accurate precise frequency measurement principle (HRA-High Rate Accuracy System) Frequencies up to 38 Hz are calculated using time-interval (period duration) measurement. Frequencies > 38 Hz are calculated using a special time base (gate time) measurement. A very high accuracy of < 0.1 % is achieved, even with very short gate times. The resulting measurement is available after a max. of 50 ms.
- Short start-up time – detects input pulses just 16 msec after being switched on => no pulses are lost with a simultaneous motor start-up.
- Large keys – can also be operated when wearing gloves.
- Programming
- Simple uniform menu-driven programming and operation.
- Possible to enter the programming also during operation with a confirmation prompt.
- Pressing the right key switches between displays.
- Individually programmable scaling: multiplication and division factor (0.0001…99.9999), to display corresponding engineering units, e.g. position in 1/10 mm and speed in RPM.
- Separate factors for frequency- and pulse counting.
- AC or DC power supply.
- Inputs : as an alternative to the HTL inputs, devices with a 5 VDC input level are available, for use as parallel displays for PLCs.
- Timer specials: timer or hours-run meter with various Start /Stop measurements, time range settings in hours, minutes or seconds, with decimal point. Resolutions up to 1/1000 can be programmed.
